Not sure if it will hold but BA2256 ANU -LGW on 5/2/24 is showing as a CS layout. Has since booking in Feb this year. Outbound is old style Club Seats. Just checked cabin looks pretty full. It will be very annoying if it reverts to the standard LGW layout as I’ve paid for seats ! Shows 56 J seats in CS but if it reverts I assume there will only be 32. It’s an Amex 2-4-1 booking so not sure if that makes me more likely to get downgraded in the event of a change - I’ll be silver by then but I don’t know if that will help.
